What is a square bottom bag? Let's take a look. Square bottom bags are mainly made of plastic. To improve the performance of square bottom bag plastics, various auxiliary materials are added, such as fillers, plasticizers, lubricants, stabilizers, and colorants. Square bottom bags are generally made of synthetic resin, with a square bottom, hence the name. It can be unfolded like a cardboard box, with different lengths, widths, and heights, and can be "custom-made" according to the different sizes of the products to be packaged.
Square bottom bags generally have five sides: front and back, two sides, and bottom. The unique structure of square bottom bags makes it very convenient to package three-dimensional or square products. This type of bag combines the packaging significance of plastic bags while fully expanding new packaging ideas, so it is now widely used in daily life and production.
Square bottom bags have two polymer structures:
1. Linear structure. High molecular compounds with this structure are called linear high molecular compounds.
3. Shape structure. High molecular compounds with this structure are called shape high molecular compounds. Some polymers have branches, called branched polymers, which belong to the linear structure. Some polymers, although there are crosslinks between molecules, have fewer crosslinks, called network structures, which belong to the bulk structure. Two different structures present two completely opposite performances.
The customization of square bottom bags requires a complex communication process before production and processing, including material combination, bag type, size, thickness, quantity, printing pattern, etc. Including details such as whether it is easy to tear, zipper, hanging hole, and vent hole. All of these need to be determined before plate making. Then, the square bottom bag manufacturer will make plates and order materials according to specific requirements and start preparing for production.
Let's take a look at the specific processing flow of square bottom bags:
1. Printing: The pattern printing of the square bottom bag is completed in this link;
2. Lamination: Laminating different material films together;
3. Curing: Put the laminated film into the curing room to make each layer of film better combined together;
4. Bag making: A complete square bottom bag is made in this way.
